Method

VipsImagethumbnail_image

Declaration [src] 

int
vips_thumbnail_image (
  VipsImage* in,
  VipsImage** out,
  int width,
  ...
)

Description [src]

Optional arguments:

  • height: %gint, target height in pixels
  • size: VipsSize, upsize, downsize, both or force
  • no_rotate: %gboolean, don’t rotate upright using orientation tag
  • crop: VipsInteresting, shrink and crop to fill target
  • linear: %gboolean, perform shrink in linear light
  • import_profile: %gchararray, fallback import ICC profile
  • export_profile: %gchararray, export ICC profile
  • intent: VipsIntent, rendering intent
  • fail_on: VipsFailOn, load error types to fail on

Exactly as vips_thumbnail(), but read from an existing image.

This operation is not able to exploit shrink-on-load features of image load libraries, so it can be much slower than vips_thumbnail() and produce poorer quality output. Only use it if you really have to.
